Chii chinonzi "air filter"?
Sefa yemhepo mudziyo unobata zvinhu zvidiki kuburikidza nekushanda kwezvinhu zvinosefa zvine maburi uye unochenesa mweya. Mushure mekucheneswa kwemhepo, inotumirwa mukati meimba kuti ive nechokwadi chekuti zvinodiwa mumakamuri akachena uye kucheneswa kwemhepo mumakamuri ane mhepo inotonhorera. Nzira dzekusefa dzinozivikanwa parizvino dzine mhedzisiro mishanu: mhedzisiro yekubata, mhedzisiro yeinertial, mhedzisiro yekuparadzira, mhedzisiro yegiravhiti, uye mhedzisiro yemagetsi.
Zvichienderana nezvinodiwa zvekushandiswa kwemaindasitiri akasiyana, mafirita emhepo anogona kukamurwa kuita mafirita ekutanga, mafirita epakati, mafirita ehepa uye mafirita e-ultra-hepa.
Ungasarudza sei firita yemhepo zvine musoro?
01. Sarudza zvine musoro kushanda kwemafirita pamatanho ese zvichienderana nemamiriro ekushandisa.
Mafirita ekutanga nepakati: Anonyanya kushandiswa mukuchenesa kwese ...
Sefa yeHepa/ultra-hepa: yakakodzera kushandiswa kwenzvimbo dzine zvinodiwa zvekuchenesa zvakanyanya, zvakaita senzvimbo dzinopa mhepo inotonhorera munzvimbo dzekuchenesa dzisina guruva muchipatara, kugadzira magirazi emagetsi, kugadzira zvishandiso zvine hungwaru uye mamwe maindasitiri.
Kazhinji, sefa yemagetsi ndiyo inosarudza kuti mhepo yakachena zvakadii. Masefa ekumusoro pamatanho ese anoita basa rekudzivirira kuti awedzere hupenyu hwebasa rawo.
Kushanda zvakanaka kwemafirita padanho rega rega kunofanirwa kugadziriswa nemazvo. Kana marongero ekushanda zvakanaka ematanho maviri ari pedyo emafirita akasiyana zvakanyanya, danho rekare harizokwanisi kuchengetedza danho rinotevera; kana musiyano uripo pakati pematanho maviri aya usina kusiyana zvakanyanya, danho rekupedzisira richaremerwa.
Chigadziro chakanaka ndechekuti kana uchishandisa "GMFEHU" efficiency specification classification, isa first-level filter mushure mematanho maviri kusvika mana.
Pamberi pesefa yehepa pamucheto wekamuri rakachena, panofanira kunge paine sefa ine hunyanzvi hwekushanda husingasviki F8 kuti idzivirire.
Kushanda kwesefa yekupedzisira kunofanirwa kuve kwakavimbika, kushanda zvakanaka uye magadzirirwo esefa isati yagadzirwa zvinofanira kunge zvine mwero, uye kugadziriswa kwesefa yekutanga kunofanirwa kunge kuri nyore.
02. Tarisa maparamita makuru efirita
Vhoriyamu yemhepo yakayerwa: Kune mafirita ane chimiro chimwe chete uye zvinhu zvakafanana zvefirita, kana kuramba kwekupedzisira kwaonekwa, nzvimbo yefirita inowedzera ne50%, uye hupenyu hwesefa huchawedzerwa ne70%-80%. Kana nzvimbo yefirita yakapetwa kaviri, hupenyu hwesefa huchareba katatu kupfuura hwepakutanga.
Kuramba kwekutanga uye kuramba kwekupedzisira kwesefa: Sefa iyi inoita kuti mhepo isafambe zvakanaka, uye guruva rinoungana pasefa rinokura nekufamba kwenguva. Kana kuramba kwesefa kwawedzera kusvika pahuwandu hwakatarwa, sefa iyi inobviswa.
Kuramba kwefirita itsva kunonzi "kuramba kwekutanga", uye kukosha kwekuramba kunoenderana nepanenge pabviswa firita kunonzi "kuramba kwekupedzisira". Mamwe masampuli efirita ane ma "parameter ekuramba kwekupedzisira", uye mainjiniya emhepo anogonawo kushandura chigadzirwa zvichienderana nemamiriro enzvimbo yacho. Kukosha kwekupedzisira kwekuramba kwedhizaini yekutanga. Kazhinji, kuramba kwekupedzisira kwefirita inoshandiswa panzvimbo yacho kunopfuura kaviri kana kane kuramba kwekutanga.
Kudzivirira kwekupedzisira kunokurudzirwa (Pa)
G3-G4 (sefa yekutanga) 100-120
F5-F6 (firita yepakati) 250-300
F7-F8 (firita yepakati nepakati) 300-400
F9-E11 (sub-hepa sefa) 400-450
H13-U17 (firita yehepa, firita yehepa yakanyanya) 400-600
Kushanda zvakanaka kwekusefa: "Kushanda zvakanaka kwekusefa" kwesefa yemhepo kunoreva huwandu hweguruva rinobatwa nesefa nehuwandu hweguruva hwemhepo yekutanga. Kuonekwa kwekushanda zvakanaka kwekusefa hakuparadzaniswi nenzira yekuedza. Kana sefa imwe chete ikaedzwa uchishandisa nzira dzakasiyana dzekuedza, kukosha kwekushanda kwakawanikwa kuchasiyana. Saka, pasina nzira dzekuedza, kushanda zvakanaka kwekusefa hazvigoneke kutaura nezvazvo.
Kugona kubata guruva: Kugona kubata guruva kwesefa kunoreva huwandu hwakanyanya kubvumidzwa hwekuunganidzwa kweguruva musefa. Kana huwandu hwekuunganidzwa kweguruva hwapfuura kukosha uku, kuramba kwesefa kuchawedzera uye kushanda kwekusefa kuchaderera. Nokudaro, zvinowanzo taurwa kuti kugona kubata guruva kwesefa kunoreva huwandu hweguruva hunounganidzwa kana kuramba nekuda kwekuunganidzwa kweguruva kwasvika pamutengo wakatarwa (kazhinji kaviri kuramba kwekutanga) pasi pehuwandu hwemhepo.
03. Tarisa bvunzo yekusefa
Kune nzira dzakawanda dzekuedza kushanda zvakanaka kwefirita: nzira yegravimetric, nzira yekuverenga guruva remumhepo, nzira yekuverenga, photometer scanning, nzira yekuverenga scanning, nezvimwewo.
Nzira yekuverenga yekuongorora (MPPS Method) Saizi yezvikamu zvinopinda zvakanyanya
Nzira yeMPPS parizvino ndiyo nzira inonyanya kushandiswa pakuongorora mafirita ehepa pasi rose, uye ndiyo nzira yakanyanya kuomarara yekuongorora mafirita ehepa.
Shandisa kaunda kuti urambe uchiongorora uye uchitarisa nzvimbo yese inobuda mweya mufirita. Kaunda iyi inopa huwandu nehukuru hweguruva panzvimbo imwe neimwe. Nzira iyi haingogoni kuyera kushanda kwesefa chete, asiwo kuenzanisa kushanda kwenzvimbo imwe neimwe.
